3D Printing vs CNC Service: How to Choose the Right Manufacturing Method

3D printing and CNC (Computer Numerical Control) service are two popular manufacturing methods that have gained widespread attention in recent years. 3D printing, also known as additive manufacturing, involves building 3D objects layer by layer from a digital model, while CNC service, also known as subtractive manufacturing, involves cutting away material from a solid block to create a desired shape. Both methods offer unique capabilities and advantages, and understanding their key characteristics is ......

Why Use PEEK 3D Printing? Benefits, Applications & Challenges

Most engineering materials get chosen because they're available, familiar, or cheap. PEEK gets chosen because nothing else works. When an engineer specifies PEEK 3D printing, it's almost always because the part needs to survive conditions that would disqualify every other plastic on the shortlist, sustained heat above 200℃, aggressive chemicals, sterilization cycles, or mechanical loads that other polymers handle poorly over time. PEEK 3D printed parts aren't “prototype outputs”. They're functional en......

How to 3D Print a Perfect Airless Basketball Without Failing

To figure out how to 3D print an airless basketball that actually bounces, you need four things: A proven airless basketball STL A bounce-optimized material (TPU or PEBA) Correct print settings A lattice structure designed for energy return Most failed prints are not caused by the printer itself. They fail because the material or structure cannot efficiently return energy during impact. This guide breaks down the exact community-tested STL files, the ultimate showdown between TPU and PEBA materials, a......

3D Printed Basketball Materials: Comparing TPU and PEBA Performance

Wilson dropped their airless basketball concept and the maker community went wild. Suddenly everyone wanted to print one. The problem is that most people grabbed whatever flexible filament they had, printed a lattice basketball, bounced it twice, and posted a disappointed video. The ball looked right. It didn't play right. The material choice is almost everything with a 3D printed airless basketball. Get it wrong and you get a ball that thunks instead of bounces, or cracks after a week of casual dribb......

The Complete B2B Buyer’s Guide to Large Scale 3D Printing Services

Most buyers discover the hard way that large format 3D printing is more complicated than just finding a company with a big machine. A supplier may provide a confident quote but still deliver a warped part late. When that happens, both time and budget are wasted. Large scale 3D printing enables manufacturers to produce oversized prototypes, tooling, molds, and end-use parts that are difficult or costly to manufacture using traditional methods. According to Wohlers Report 2026, the global additive manuf......
